ABSTRACT:
In a VTR for a TCI signal, time-base correction and TCI decode processing are applied to the reproduced TCI signal of each channel and also to the corresponding dropout signals. According to the resulting dropout signal for luminance signal and the dropout signal for chrominance signal, the dropout section of a luminance signal and the dropout section of a chrominance signal are respectively compensated for. As a result, a luminance signal may have the data of the dropout section compensated for with data of a highly correlated luminance signal of 1H before and 1H after the horizontal period where dropout occurs. The dropout compensation circuits can be simplified since the luminance and chrominance signals are processed by separate circuits.
